PROTRONIX ADS-RH-D Duct Mounted Relative Humidity Sensor User Manual

ADS-RH-D is used to control ventilation, heat recovery and air conditioning systems by measuring relative humidity in the air duct.

  • relative humidity measuring
  • analog voltage / current output
  • output relay
  • fully calibrated
  • long-term stability

Description

ADS-RH-D is a capacitive relative humidity (RH) sensor.
It is equipped with an output relay with adjustable switching level and with analog 0-10V voltage / 0- 20mA (4-20mA) current output. The measurement is performed periodically after about 8s.

Based on these measurements it is possible to directly control the ventilation, air conditioning and heat recovery units.

Internal layout

Relay switching level adjustment trimmer

  • turn to the left to decrease the relay switching level of RH, the relay will switch at lower RH level
  • turn to the right to increase the relay switching level of RH, the relay will switch at higher RH level

To avoid fast relay switching around the adjusted level the hysteresis of 15% is added automatically.

Voltage / current output petting – jumper JP1

  • Jumper in position U = voltage output.

  • Jumper in position I = current output.

Current output petting – jumper JP2

  • Jumper fitted = output 4-20mA.

  • Jumper not fitted = output 0-20mA.

LED indication

Blue

  • relay contacts closed = indication is on
  • relay contacts opened = indication is off

LED indication setting – jumper JP5:

  • Jumper fitted = LED enabled.

  • Jumper not fitted = LED disabled.

Installation

Installation Induction

If you connect other devices to the same AC power source as the ADS sensor, it is necessary to meet GND wiring of all analog inputs and outputs, as well as power wires.
